Continuous Read Mode Reset (CRMR) (FFH)
The Dual/Quad I/O Fast Read operations, “Continuous Read Mode” bits (M7-0) are implemented to
further reduce command overhead. By setting the (M7-0) to AXH, the next Dual/Quad I/O Fast Read
operations do not require the BBH/EBH/E7H command code.
Because the ACE25C100G has no hardware reset pin, so if Continuous Read Mode bits are set to
“AXH”, the ACE25C100G will not recognize any standard SPI commands. So Continuous Read Mode
Reset command will release the Continuous Read Mode from the “AXH” state and allow standard SPI
command to be recognized. The command sequence is show in Figure24.
